Description

The present invention relates to a clip mounting structure for mounting a clip to a cylindrical body such as a shaft or cap of a writing instrument or a cosmetic.
Specifically, the present invention relates to a clip mounting structure in which a cylindrical body such as a shaft cylinder or a cap and a clip are attached by pressing fitting of a locking projection and a locking recess formed respectively.

  Conventionally, as this type of clip mounting structure, a clip mounting part protrudes from the outer surface of the cylindrical body, and convex portions are formed as holding parts on both side surfaces of the clip mounting part, and are mounted on both sides behind the clip. A mounting portion is formed with one side bent in a face-to-face shape toward the back side, and a hole is formed as a locking portion in the both mounting pieces, so that the mounting portion of the clip covers the clip mounting portion of the cylindrical body When the one-touch operation of pushing into the mounting part causes both mounting pieces of the mounting part to be pushed outward, and when the hole-shaped locking part matches the convex holding part, the two mounting pieces that have been pushed outward are restored. There is one in which the hole-shaped locking portion is fitted into the convex holding portion by the restoring force to return to the above state, and the clip is fixedly held on the cylindrical body (see, for example, Patent Document 1).

JP 2004-174931 A (page 4-5, FIG. 1-5)

  However, in such a conventional clip mounting structure, since the hole-shaped locking portion and the convex holding portion are exposed on the surface of the clip, not only the appearance is inferior, but also the limitation on the design of the clip. As a result, there is a problem that it may not be adopted for high-grade products.

The first invention of the present invention aims at completely hiding the indentation fitting portion in the clip.
Furthermore , the object is to produce a clip that is difficult to shake during push-in fitting by a simple bending process.
The third invention is, in addition to the first inventions of interest is intended to provide a spring portion can be secured a lever type (binder-type) clip without increasing the overall area of the clip.

In order to achieve the above-described object, the first invention of the present invention is characterized in that a cylindrical body such as a shaft cylinder or a cap, and a clip formed by bending a raw material plate are respectively formed with a locking projection and A clip mounting structure that is mounted by pushing-fitting the locking recess, and a tip portion formed by forming a pair of mounting pieces so as to sandwich the mounting recess in the clip and extending to the tip side of the mounting piece Are bent toward the mounting recess so as to overlap the mounting piece, and either the locking projection or the locking recess is opposed to the mounting projection protruding from the cylindrical body. provided, the other of the engagement projections or the locking recess provided at a position facing the attachment member of the cylindrical body, with the pushing of the clip relative to the attachment member of the cylindrical body, the clip is elastically deformed to the attachment in the recess It is characterized in that fitted to the engagement concave portion and the locking projections.
The second invention is characterized in that a configuration in which the outer surface of the mounting piece is formed flat is added to the configuration of the first invention.
The third invention is the construction of the first invention or the second invention, the engaging and convexed latch portion and rotatably fitted with the locking recess, the clip to the attachment member of the cylindrical body as well as pivotally mounted to, notch an inner portion of the clip partially bent the cut portion, integral spring portion which elastically presses toward the distal clamping portion of the clip to the tubular body It is characterized by adding the formed structure.

According to a first aspect of the present invention, either one of the locking projection and the locking recess is provided on the inner surface of the mounting recess formed on the clip so as to face the mounting projection formed on the cylindrical body. The other of the locking projection and the locking recess is provided at a position opposite the mounting projection of the cylinder, and the clip is elastically deformed as the clip is pushed into the mounting projection of the cylinder. By fitting the latching projection and the latching recess in the recess, the fitting portion of the latching projection and the latching recess is covered with the wall surface surrounding the mounting recess and is not exposed.
Therefore, it is possible to completely hide the fitting-in place in the clip.
As a result, compared with the conventional one in which the hole-like locking portion and the convex holding portion are exposed on the surface of the clip, the appearance is excellent, the degree of design freedom is increased, and it can be used for high-grade products.

Furthermore, forming a pair of mounting pieces so as to sandwich the recess Mounting clip, bending the tip portion which is formed by extending the front end side of the mounting piece portion, so as to overlap the respective mounting piece portion toward the mounting recess By forming a pair of either the locking projections or the locking recesses, the strength of the entire mounting piece is improved and is difficult to be deformed. A recess is disposed.
Therefore, it is possible to manufacture a clip that is difficult to swing during push-in fitting by a simple bending process.
As a result, a clip excellent not only in design but also in functionality can be manufactured at low cost.

In addition to the effects of the first invention or the second invention, the third invention is configured such that the locking projection and the locking recess are rotatably fitted to swing the clip with respect to the mounting projection of the cylinder. By freely mounting, by partially notching the inner part of this clip, bending this notch part, and integrally forming a spring part that elastically presses the tip clamping part of the clip toward the cylinder The notch inside the clip is used as a spring part that is elastically deformed as the clip swings.
Therefore, it is possible to provide a lever type (binder type) clip that can secure the spring portion without increasing the entire area of the clip.
As a result, the punching area of the entire clip can be reduced, and the number of punches per sheet of raw material can be increased, so that the manufacturing cost can be reduced.

  As shown in FIGS. 1 to 3, the clip mounting structure A according to an embodiment of the present invention has a mounting protrusion 1 a formed at a predetermined position of a cylindrical body 1 such as a writing tube or a shaft of a makeup tool, or the clip 2. A locking recess formed on each of the mounting projection 1a and the mounting recess 2a by a one-touch operation in which the mounting recess 2a is formed at a predetermined position and the mounting projection 1a of the cylinder 1 is pushed so as to cover the mounting recess 2a of the clip 2. The protrusions 3 and the locking recesses 4 are fitted, and the clip 2 is attached to the cylindrical body 1.

  The cylindrical body 1 is formed in a cylindrical shape from a synthetic resin or a similar material, and a substantially rectangular parallelepiped mounting convex portion 1a is integrally formed or integrally formed at a predetermined position on the outer surface thereof. A pair of both side surfaces of the mounting convex portion 1a are opposed to a pair of mounting piece portions 2b described later.

  The clip 2 has a predetermined three-dimensional shape by punching and bending a raw material plate (not shown) formed of a metal that can be elastically deformed into a predetermined shape by pressing or the like, or by integrally molding a synthetic resin or the like. A mounting recess 2a having a width dimension that fits the mounting projection 1a is formed at least on the rear side in the longitudinal direction of the inner surface (left side in FIG. 1A). A pair of attachment piece portions 2b are formed so as to be sandwiched.

  Then, on the inner surface of the mounting recess 2a of the clip 2, either one of the locking projection 3 or the locking recess 4 is provided facing the mounting projection 1a of the cylindrical body 1, and these locking The other of the convex portion 3 and the locking concave portion 4 is provided at a position opposite to the mounting convex portion 1a of the cylindrical body 1, and by pressing the mounting concave portion 2a of the clip 2 against the mounting convex portion 1a of the cylindrical body 1 described above, Both attachment piece portions 2b of the clip 2 are elastically deformed and gradually open, and the engagement protrusion 3 and the engagement recess 4 are fitted in the attachment recess 2a.

  As an example, by bending both mounting pieces 2b of the clip 2 into a U-shaped cross section, a mounting recess 2a is formed between the mounting pieces 2b, and the tip of each mounting piece 2b. 2c is bent toward the mounting recess 2a and folded twice or folded back into a substantially V-shaped cross section to improve the strength of each mounting piece 2b and make it difficult to deform. A pair of either the locking projection 3 or the locking recess 4 is formed in the mounting recess 2a.

Further, the fitting state of the locking projections 3 and the locking recesses 4 is brought into close contact with each other, and the mounting recess 2a of the clip 2 is mounted immovably on the mounting projection 1a of the cylindrical body 1, or The engaging projection 3 and the engaging recess 4 are rotatably fitted, and the clip 2 is attached to the mounting projection 1 a of the cylinder 1 so as to be swingable.
Embodiments of the present invention will be described below with reference to the drawings.

  In the first embodiment, as shown in FIGS. 1 (a), 1 (b), and 2, a latching protrusion 3 is provided on both side surfaces of the mounting protrusion 1a of the cylindrical body 1, and the clips are opposed to these. 2, the locking recesses 4 are respectively provided in the mounting recesses 2 a, and the locking protrusions 3 and the locking recesses 4 are fitted in close contact with each other by the push-in one-touch operation described above. The case where the attachment recessed part 2a of the clip 2 is mounted | worn so that it cannot move with respect to the attachment convex part 1a is shown.

Specifically, at the stage of punching the raw material plate of the clip 2 with a press machine or the like, a locking recess 4 is formed in advance at the tip 2c of each mounting piece 2b, and the mounting pieces 2b are bent into a U-shaped cross section. While processing, the front-end | tip part 2c is turned up toward the attachment recessed part 2a, respectively, and the latching recessed part 4 is arrange | positioned toward the attachment recessed part 2a at these turned-up parts 2c, respectively.
As another example, it is also possible to form a hole-shaped locking recess 4 by opening a hole in the tip 2c of the mounting piece 2b.

  Furthermore, as shown in FIG. 1B, the distal end surfaces of the locking projections 3 formed on both side surfaces of the mounting projection 1 a of the cylinder 1 are gradually moved toward the outer surface of the cylinder 1. It is preferable to incline in a taper shape that expands. Similarly, the opposing tip portion 2c of the mounting piece 2b is gradually expanded from the back side of the mounting recess 2a toward the opening end by the bending process described above. It is preferable to incline in a tapered shape.

  In the case of the illustrated example, the cylinder 1 is a shaft cylinder of a writing instrument, and the front side in the longitudinal direction of the inner surface of the clip 2 (on the right side in FIG. 1A) faces the outer surface of the cylinder 1. While the ball portion is formed by bending as the tip clamping portion 2d, the locking projection 3 and the locking recess 4 are engaged with each other in a substantially rectangular shape so as to be non-rotatable. It is also possible to form the convex portion 3 and the locking concave portion 4 in a shape other than the illustrated example, such as a substantially circular shape or an elliptical shape that fits each other.

Next, the attachment method and operation effects of the clip attachment structure A will be described.
First, the clip 2 bent as shown in FIG. 2 is positioned so that its mounting recess 2a faces the mounting projection 1a of the cylindrical body 1, as shown by the alternate long and short dash line in FIG. The mounting recess 2a is pushed in so as to cover the mounting projection 1a of the cylindrical body 1 as it is.

  As a result, the opposing tip 2c of the mounting piece 2b abuts on both side surfaces of the mounting projection 1a of the cylindrical body 1, and as a result, as shown by the two-dot chain line in FIG. Each of the portions 2b is elastically pushed outward (left and right sides in FIG. 1), and can be pushed further.

  And each latching recessed part 4 formed in the inner surface of the attachment recessed part 2a of the clip 2 is pushed in to each latching convex part 3 formed in the both sides | surfaces of the mounting convex part 1a of the cylinder 1, and these match. Then, each of the locking recesses 4 is fitted into each of the locking projections 3 by the elastic restoring force of both the mounting piece portions 2b, so that the clip 2 is a cylinder as shown by the solid lines in FIGS. The fixing projection 1a of the body 1 is fixed and held.

In this mounted state, the fitting portions of the locking projections 3 and the locking recesses 4 are not covered and exposed by the mounting piece portions 2b that are the wall surfaces surrounding the mounting recesses 2a. Can be completely hidden.
Furthermore, when the locking recesses 4 are formed by bending the tip portions 2c of the mounting pieces 2b toward the mounting recesses 2a, the strength of the mounting pieces 2b as a whole is improved and it is difficult to deform. In addition, there is an advantage that the clip 2 is less likely to swing with respect to the mounting convex portion 1a of the cylindrical body 1 and can be prevented from being loose when attached.

  In the second embodiment, as shown in FIGS. 3A and 3B, the locking projection 3 is formed in a substantially columnar shape, and is engaged with the locking recess 4 so as to be freely rotatable. The configuration in which the clip 2 is swingably attached to the mounting convex portion 1a is different from the first embodiment shown in FIGS. 1 to 2, and the other configurations are shown in FIGS. This is the same as Example 1.

Specifically, at the stage of punching the raw material plate of the clip 2 with a press machine or the like, the outer shape of the mounting piece portion 2b is formed in a substantially semicircular shape, and the arc-shaped concave portion serving as the locking concave portion 4 is dispersed at the tip portion 2c. The mounting piece 2b is bent into a U-shaped cross section, and the tip 2c is folded back toward the mounting recess 2a, so that the side shape of the mounting piece 2b is substantially semicircular. Thus, in each folded portion 2c, an arcuate recess is disposed toward the mounting recess 2a as a locking recess 4 that is rotatably fitted to the substantially cylindrical locking projection 3. .
As another example, it is also possible to form a hole-shaped locking recess 4 by opening a hole in the tip 2c of the mounting piece 2b.

  Further, the clip 2 is partially cut out at the inner portion, the cutout portion 2e is bent, and a spring portion 2f that elastically presses the tip clamping portion 2d of the clip 2 toward the cylindrical body B is integrated. By doing so, the case where the notch 2e inside the clip 2 is a lever type (binder type) clip used as a spring part 2f that is elastically deformed as the clip 2 swings is shown.

  That is, the clip 2 is characterized in that when the outer shape of the clip 2 is punched out with a press or the like, the inner portion thereof is partially cut out, and the cutout portion 2e is formed into a predetermined shape. The end portion 2g is grounded or brought close to the outer surface of the cylindrical body 1 by bending and thereby the spring portion 2f is integrally formed, and the tip clamping portion 2d is formed by the spring force of the spring portion 2f. 1 is elastically pressed toward 1.

  As a specific example, a substantially center inner portion of the clip 2 is cut out linearly in the longitudinal direction, the straight cutout portion 2e is bent into a substantially U shape or a V shape, and the end portion 2g is formed into a cylinder. It is preferable that the whole or part of the notch portion 2e functions as the spring portion 2f by being grounded to the outer surface of the body 1 or by being grounded and locked to the mounting convex portion 1a of the cylindrical body 1.

  In the case of the illustrated example, it is bent from the root portion of the notch portion 2e of the clip 2 and is behind the rotational fitting position of the locking convex portion 3 and the locking concave portion 4 (on the left side in FIG. 3A). In addition, the spring portion 2f is formed so as not to interfere with the mounting convex portion 1a of the cylindrical body 1.

  Thereby, first, when the operation part 2h on the rear end side of the clip 2 shown by the solid line in FIG. 3A is not pushed toward the cylindrical body 1, the tip end of the clip 2 is clamped by the spring force of the spring part 2f. The part 2d is elastically pressed toward the outer surface of the cylindrical body 1 and is in contact therewith.

  From this state, as shown by a two-dot chain line in FIG. 3A, when the operation portion 2h of the clip 2 is pressed to the cylindrical body 1, the spring portion 2f is elastically compressed and deformed, and the locking projection 3 and The clip 2 as a whole swings around the rotation fitting position of the locking recess 4, and the tip clamping portion 2 d is separated from the outer surface of the cylinder 1, so that not only a thin adherend such as a clothing pocket but also a Can also be sandwiched and held in a thick notebook or board.

  Therefore, the second embodiment shown in FIGS. 3 (a) and 3 (b) has the same effect as that of the first embodiment described above, and is further disclosed in, for example, FIG. 7 of JP-A-2004-82533. Compared to a case in which such a spring portion extends integrally from the clip in the longitudinal direction, there is an advantage that a lever-type clip that can secure the spring portion without increasing the entire area of the clip 2 can be provided.

In the previous embodiment, the locking projections 3 are provided on both side surfaces of the mounting projection 1a of the cylindrical body 1, and the locking recess 4 is provided in the mounting recess 2a of the clip 2 facing this. However, the present invention is not limited to this, but although not shown, a locking recess is provided on both side surfaces of the mounting projection 1a of the cylindrical body 1, and a locking projection is formed in the mounting recess 2a of the clip 2 opposed thereto. You may do it.
At this time, a locking projection is formed in advance on the tip 2c of each attachment piece 2b of the clip 2, and each of the attachment pieces 2b is bent into a U-shaped cross section, and the tip 2c is attached to the attachment recess 2a. It is preferable that the locking projections are arranged in the folded-back portions 2c toward the mounting recesses 2a by folding them back, respectively.
Furthermore, in the illustrated example, the case where the cylindrical body 1 is a shaft cylinder of a writing instrument is shown. However, the present invention is not limited to this. For example, it is a shaft cylinder of a cosmetic tool other than a writing instrument, and is detachable from these shaft cylinders. A cap to be inserted may be used.
Therefore, in this case, the same effect as the above-described embodiment can be obtained.
